Abstract
Complex traces of sedimentary hydrocarbons up to C31H64 were examined by combined GC-MS for evidence of biological origin. The system described can analyze a complex extract of 10−4–10−5 g in a single sampling. Where GC separation permitted, individual hydrocarbons amounting to less than 10−7 g were identified. The hydrocarbon distribution in the very old Onverwacht sedimentary rock was compared and contrasted with that found in a recent unconsolidated Santa Barbara Basin sediment.Keywords
